I have done gobs of reading past posts here and on the other light backpacking site and from what I gather, no. One guy did a 21 day test with some since that is what it said on his package, he dug it up and it was just as it was when he buried it. The consensus is that if you pour water into the cathole and stir everything around, this truly speeds up decomposition.

Don't know what you know or don't know; but the big thing about burying it, is that animals will dig it up and drag the TP out of the hole.

So, no, I wouldn't bury it, and ruin someones else's hiking experience by having to see toilet paper scattered all over the woods. I have actually seen this.
